We are all well acquainted with Earth, but try to think about Earth in the same way you think about the other planets.
Earth is the third planet from the Sun, and it orbits in a near-circular ellipse.
The planet Earth is about the same size as Venus, and it has the same mass and density, but the similarities stop there.
Most of Earth’s surface, about 70 percent, is covered by water, and the landmasses appear to have once been joined.
Active volcanoes and earthquakes are in evidence.
Earth has one satellite, which we know as the Moon.
Perhaps the most interesting feature of this planet is the existence of life.
